LIBRARY OR OTHER SHELVING.

SPECIFICATION forming part of Letters Patent Ala 644,228, dated February 27, 1900.

Application filed December 8, 1898. Serial No. 698,664- (No model.)

To all whom it may concern: 7 Be it known that I, PAUL L. HAY, a citizen of the United States, residing at Pittsburg, in the county of Allegheny, State of Pennsylvania, have invented or discovered certain new and useful Improvements in Library or other Shelving, of which improvement the following is a specification. I

This invention relates to improvements in library and other shelving; and among the objects of this invention are to provide a new and improved shelving, a shelving adapted for one or more storied stacks, andnew and improved means for adjusting each shelf.

With these objects in View thisinvention consists in a new and improved shelving and in certain new features of construction and combination of parts, all as hereinafter fully set forth.

In the accompanying drawings, which illus trate an application of my invention, Figure 1 is a perspective view; Fig. 2, a side elevational view of upright, bracket, and means for securing the bracket to the upright orstandard; Fig. 3, a plan view of the same; Fig. 4, an enlarged perspective view of a portion of the upright, showing the manner of securing the bracketto the upright; Fig. 5, detail sectional views of modified forms of uprights, and Fig. 6 a cross-section on line 00 m of Fig. 2 looking upward.

Referring to the drawings, 1 represents a standard or upright, preferably made of metal and in the form shown. The standards for the intermediate stacks, as illustrated, oomprise what may be termed a double I-b'eam. This standard or upright 1, having the flanges 2, is of such a design that it may be rolled from steel or cast from other metal, or it may be made of wood or other suitable material.

In Fig. 5 of the drawings I have shown seetional views of modified forms of standards, all of which, however, are provided with flanges 2. The standards shown by this figure are particularly adaptable for end and wall standards.

Brackets 3 to receive and support a shelf 4 are adapted to be adjustably fastened to the uprights. The brackets 3 are at present preferably made as shown by the drawings and may be made in one piece from steel, iron, or other suitable material. Each bracket is provided with a guideway and supportingledge for the shelf at and an underbrace 5, which latter is'adapted tobear against the outer face of the flanged portion of the standards. A rearwardly-extending part 6 of the bracket is provided with apertured lugs 7, through which threaded bolts 8 and 9 are adapted to pass. Lugs 10 on the bracket are so disposed thereon that when the bracket is applied to the uprights the lugs 10 will come on both sides of the flange 2, and the function of these lugs is to aid in maintaining the brackets in proper position. The threaded bolts 8 and 9, one of which has a right-hand thread and the other a left-hand thread, enter into and engage with an internally-threaded sleeve or nut 11. The threads of the sleeve or nut 11 correspond with the threads of the bolts 8 and 9that is to say, the threaded portion of the sleeve or nut is partly a right-hand thread and partly a left-hand thread. The headsof the bolts 8 and 9 are adapted to come in contact with and bear against the flanges 2 of the standards, and the threaded ends of both bolts enter into the sleeve or nut 11 and engage with the threads thereon. For the purpose of conveniently turning the sleeve or nut I provide a pin 12, located in a small hole in the sleeve.

The heads of the bolts, which are adapted to bear against the flanges of the standards, may be of any preferred shape and material or materials. They are moved toward and away from the flanges by turning the internally-threaded sleeve or not 11.

In Fig. l of the drawings I have shown a simple and convenient construction for two stories of stacks. In this construction 13 and 14 represent portions of the floor systems, on which is located glass or ot'her suitable fioor= ing 15. The standardsil arebraced at their lower ends by cross-pieces lo and by adj ustable rods 17 which are connected with the standards by means of the bent plates 20 and pins 21.

Among the requisites for good shelving, and particularly for library-shelving, the followin g, which are embodied in myinvention, may be mentioned: The shelves are readily adj ustable to any desired position. The stack is free from any rough surface liable to inj ure books. The construction shown is adapted for one or several storied stacks and is constructed in such a manner as to cause very little obstruction to light and air. Attention is also called to the fact that the shelves will not slip downward. The greatest weight on library-shelves is placed on the front of the shelves, and this being the case the under brace 5 of the bracket and its lugs are so situated that the greatest strain will fall on them. This underbrace bearing against the standard, together with the lugs 10 on both sides of the flange 2,is capable of sustaining a very great Weight.

IVhat I claim is- 1. In library or other shelving, the combination, with an upright having a plain outer face, longitudinal grooves in the sides thereof and straight flanges at right angles to the body, of a bracket comprising an underbrace bearing against the outer face of the upright, a rearwardly-extending portion provided with means, located between the flanges, for engaging a clamping device, a clamping device arranged between the flanges to engage with the rearwardly extending portion of the bracket and with the flanges, substantially as set forth.

2. In library or other shelving, the combination, with an upright having a plain outer face, longitudinal grooves in the sides thereof and straight flanges at right angles to the body, of a bracket comprising an under-brace bearing against the outer face of the upright, means, as 10, engaging with a flange of the upright, a rearwardly-extending portion provided with lugs, located between the flanges, for engaging a clamping device, a clamping device arranged between the flanges to engage with the lugs and with the flanges, substantially as set forth.

3. In library or other shelving, the combination, with an upright having a plain outer face, longitudinal grooves in the sides thereof and flanges at right angles to the body, of a bracket bearing against the outer face and comprising a rearWardly-extending portion having apertured lugs located between the flanges a clamping device comprising threaded bolts and a screw-threaded sleeve or nut arranged between the flanges and adapted to engage with the apertured lugs and the flanges, substantially as set forth.

4. In library or other shelving, the combination, with flanged uprights, of brackets carrying a shelf, each bracket provided with an underbrace, 5, a rcarWardly-extending part provided with apertured lugs, and clamping means comprising a right hand threaded bolt, a left-hand-threaded bolt and an internally-threaded sleeve or nut, said bolts pass ing through the apertured lugs and having their threaded ends within the sleeve or nut and their other ends adapted to bear against a flange on the uprights, substantially as set forth.

5. In library or other shelving, the combination,with a flanged upright or standard 1, of a bracket 3, having an underbrace 5, bearing against the outer face of. the standard, lugs, as 10, engaging with a flange of the standard, a rearwardly extending portion having apertured lugs located between the flanges,a clamping device between the flanges, comprising screw-threaded bolts and a screwthreaded sleeve or nut, said clamp adapted to engage with the apertured lugs and with the flanges, substantially as set forth.

In testimony whereof I have hereunto set my hand.

PAUL L. HAY.
